TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Oct. 4, 1910.

Application filed July 22, 1910. Serial No. 573,231.

To all whom it may concern:

Be it known that I, GEORGE F. BALLoU, a citizen of the United States, and resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, .of which the following is a specification.

My invention relates to typewriting machines and more particularly to tabulating mechanism.

The invention has some of the same general objects in view as the constructions disclosed in the applications of Sivertsen & Nielsen, Serial No. 488,675; George H. Smith, Serial No. 533,717; Clio B. Yaw, Serial No. 564,227; Oscar Woodward, Serial No. 565,846; and my own application, Serial No. 541,995.

One of the main objects of the present construction, generally stated, is to provide means for readily selecting different column stops for use and for clearing the column stops which are in the operative position when the character of the work is such as to require the use of another and different set of column stops. I

The present invention is directed more particularly to the resetting mechanism by which the column stops are cleared or moved to normal or inoperative position, the object being to provide comparatively simple and efficient mechanism for quickly moving the column stops to inoperative position.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices to be hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate corresponding parts in the various views, Figure 1 is a fragmentary side elevation with parts in section of a typewriting machine embodying my invention, only so much of the machine being shown as is necessary to illustrate my invention in its embodiment therein. Fig. 2 is an enlarged detail fragmentary plan view with parts in section, the view showing the column stops and a part of the restoring mechanism. Fig. 3 is a side elevation, with parts removed, of the restoring mechanism. Fig. 4 is a front view of the upper portion of the tabulator frame, together with the support formed thereon for the parts of the restoring mechanism. Fig. 5 is a detail per spectiveview of the resetting cam. Fig. 6 is an enlarged detail end elevation of the actuating pinion and the crank carried thereby. Fig. 7 is a sectional view of the same. Fig. 8 is a detail plan view of a modified form of restoring mechanism. Fig. 9 is a sectional view of the same, taken on the line wm of Fig. 8 and looking in the direction of the arrow at said line. Fig. 10 is a front view of the construction shown in Figs. 8 and 9. Fig. 11 is a plan view of a still fur ther modified form of restoring mechanism. Fig. 12 is a side view of the same. Fig. 13 is a detail perspective view of the cam employed in the construction shown in Figs. 11 and 12.

I have shown my invention in the present instance applied to a No. 11 Remington machine though it should be understood that the invention may be embodied in various styles of typewriting machines.

The frame of the machine comprises a base 1, corner posts 2 and a top plate 3. A carriage 4c is mounted on anti-friction balls or rollers 5 that travel from side to side of the machine over the top plate. A cylindrical platen 6 is shown mounted in a conventional manner to receive the impact of the types 7 against the front face thereof.

Rearwardly extending arms 8 are secured by screws 9 to the ends of the carriage and support, at their rear ends, a column stop bar 10. The column stop bar is provided with teeth on the upper or lower sides thereof and bifurcated column stops 11 are received in the interdental spaces between the teeth and are adapted to slide fore and aft of the machine, into and out of operative position; the stops being maintained indefinitely in either of the positions to which they are moved by a frictional engagement with the walls of the interdental spaces. Each column stop is provided with a de pending lug 12 which cooperates with a bar 13 detachably secured to the column stop bar by screws 14. The bar 13 extends into the path of the depending projections 12 and limits the rearward movements of the column stops and prevents accidental displacement of the column stops from the bar. There are preferably as many interdental spaces as there are letter space positions of the carriage in its travel from side to side of the machine; or as there are letter space indices on the carriage scale 15 with which a fixed pointer 16 co'ciperates.

Any suitable tabulator mechanism may be employed to cooperate with the column stops. In the present instance I have shown denominational stop mechanism such as that employed in the No. 11 Remington machine. Thus a tabulator frame 17 is secured to the frame of the machine by screws 18 and 19. Denominational stop levers 20 are fulcrumed at 21 and project upwardly and forwardly to form denominational stops 22 at the free ends thereof. The stops 22 pass through and are guided in openings in a detachable guide plate 22 The lower ends of the denominational stop levers are connected to links 23, each of which is connected at its forward end to a depending arm 24 of an angular actuating lever pivoted on a rod 25, secured to the base of the machine. The forwardly extending arm 26 of each angular actuating lever is operatively connected to a key stem 27 guided in openings in guide plates 28 and 29. Each key stem 27 is provided with the usual tabulator key 30. Each angular actuating lever has connected thereto a coiled spring 31, the opposite end of which is connected to the guide plate 29. Each of the restoring springs is effective to restore its associated actuating lever and the parts connected therewith to the normal position. It will be understood that a depression of any of the tabulator keys is effective to move the associated denominational stop 22 into the path of those column stops which have been moved rearwardly on the column stop bar to operative position and to release the carriage by suitable means not shown.

In order to select the different column stops and to move them rearwardly to operative position, I have provided a controlling device, finger or projecting device 32 which is in the nature of a crank arm which projects from a rock shaft 33 mounted to turn in bearing openings in a bracket 34 secured to the top plate of the machine. The rock shaft 33 also has a rearwardly projecting crank arm 35 to which is connected the upper end of an actuating link 36. The lower end of this link is connected at 37 to an actuating lever 38, fulcrumed at 39 and extending forward to the key board of the machine, where it is provided with a projecting key 40. A restoring spring 41 is connected at one end to the key lever 38 and at its opposite end to a plate 42. This spring is effective to restore the key lever 38 and the parts controlled thereby to normal position. The engaging portion of the finger 32 extends forwardly of the column stop bar and, as will be seen by reference to Fig. 2, is located in substantial alinement fore and aft of the machine with the lefthand, or decimal stop, of the series of denominational stops 22. The projecting device 32 being carried by the frame of the machine and the column stops being carried by the carriage, it follows that a movement of the carriage is effective to bring about a relative movement between the column stops and the projecting device, to bring the different column stops successively into register with the contact portion of the projecting device It will be observed that the width of the contact portion of the projecting device is such that it can cooperate with but one column stop at a time. A depression of the projecting key 40 is therefore effective to move the particular column stop which is in register with the contact portion of the projecting device 32 rearwardly to the operative position, and as the carriage continues to move the different column stops are brought successively into register with the projecting device.

As hereinbefore indicated, the present invention is directed more particularly to the means for restoring the column stops to normal or inoperative position or for clearing them when the character of the work is such as to require the use of a new and different set of column stops. This mechanism will now be described.

I preferably form as an integral part of the tabulator frame a casting or extension 43 on the left-hand side thereof. This extension constitutes a bearing for the various working parts of the resetting mechanism. Referring more particularly to Figs. 1 to 7 inclusive, it will be seen that the left-hand side of this extension is formed with a channel or cut-out 44 which is angular in crosssection, conforming in shape to the stem 45 of a restoring, resetting, or contact device or cam 46 provided with oppositely inclined contact faces 47. The stem 45 is adapted to be received in the channel 44 and the walls of said channel constitute a bearing for the stem and its cam to afford a sliding movement thereof fore and aft of the machine, from the full to the dotted line position indicated in Fig. 2 and vice versa. A cover plate 48 is secured to the face of the extension 43 by screws 49, received at their threaded ends in tapped openings in the extension. The cover plate thus closes the channel 44, and when in place prevents the stem 45 from being removed laterally from the channel 44. By making the channel in the outer side of the casting in the manner specified and providing the cover plate 48, I am enabled to facilitate the manufacture of the parts and an assemblage or dismounting thereof as will hereinafter more clearly appear. The stem 45 of the cam is provided with a transverse slot 50 to receive a crank pin 51 which projects from the outer face of av disk 52. This disk is secured to one end of a pinion 53. The casting of which the projection 13 forms a part is bored out to receive the pinion 53 and the disk 52, as indicated in Fig. 2. The openings thus formed in the casting provides a bearing for the pinion and its disk to afford a turning movement thereof. A vertically disposed cylindrical opening 5a is likewise formed in the casting at right angles to the opening .in which the pinion 53 is received. This opening 54: is adapted to receive a cylindrical stem 55 of an actuating device, which at its upper end is provided with a finger piece or key 56 arranged above the tabulator frame. One side of the stem 55 provided with teeth 57 to form a rack which meshes with the pinion 53. The actuating device 55-56 has a rectilinear movement and is normally maintained in the elevated position by a coiled expansion spring 58, which is received in the opening 54 and bears at its lower end against the bottom wall of the opening, and at its upper end against the lower end of the stem 55. The shoulder 59 at the junction between the stem and the finger piece 56 is adapted to bear against the top of the tabulator frame to limit the downward movement of the actuating device 5556. The upward movement of the actuating device is limited by the engagement of the head of the cam 46 with the front face of the tabulator frame, as indicated in Fig. 2; it being understood that the positive connections between the sliding cam and its actuating device 5556 limits the upward movement of the latter.

In the operation of the resetting device it is merely necessary to depress the finger piece 56 against the pressure of the spring 58. This is effective to turn the rotative de vice, comprising the pinion 53, disk 52, and crank pin 51, through the engagement of the rack 57 with the pinion. The rotative movement thus transmitted to the rotative device from the rectilinearly movable actuating device is effective to move the cam from the full to the dotted line position in Fig. 2 where the cam is cooperative with the column stops which have been moved rearwardly to the operative position. The effect of the depression of the finger piece 56 is to move the crank pin from the position shown in Fig. 3, and from the full line position shown in Fig. 6 to the dotted line position indicated in the last mentioned figure. In other words, when the cam has been projected to operative position the crank pin 51 will have moved to the dotted line position in Fig. 6 where it will be inter posed between the axis of the pinion 53 and the cam to form a dead center arrangement which will resist any pressure exerted by the column stops against the face of the cam,

which might tend-ordinarily to restore the cam to normal position. It will thus be understood that when the cam has been projected to operative posit-ion and the carriage is moved in either direction the operative column stops will be brought successively into eoiiperative relation with one or another of the inclined faces of the cam, and will be cammed forwardly to inoperativeposition, and that the cooperation of the column stops with the cam to bring about the restoration of the column stops to inoperative position is inefiective to move the cam .rearwardly by reason of the dead center arrangement of the crank pin 51 at this time. lVhen pressure is released on the finger piece 56 the spring 58 is effective to break the dead center arrangement by moving the crank pin 51 to the full line position represented in Fig. 6 and to the position shown in Fig. 3, thereby positively withdrawing the cam to the inoperative position where it is out of cooperative relation with the operative column stops.

From the foregoing description itwill be understood that I have provided a simple and efficient construction for restoring the column stops to inoperative position, or for clearing them, and that the construction comprises but few parts and is easy to manufacture and assemble.

In Figs. 8, 9 and 10 I have shown a modified form of construction in which the cam 46 is provided with a cylindrical stem 45* formed with a tapped opening 60 therein. The tapped opening is adapted to receive a threaded hub 61 formed on and concentric with a pinion 53. A corresponding threaded hub 62 is formed at the opposite side of the pinion. This hub is received in a threaded opening in a sleeve 63 provided with a circumferential flange 6 1 and with a nick G3 for a screw driver. The sleeve may be screwed into place on the hub 62 until the flange 6-1 is seated against the inner Wall of the recess in the casting in which said flange is received. A nut (35 is then threaded into place in the tapped opening in the bearing 43 and bears at its inner end against the flange Get to force the flange against said inn-er bearing wall thus holding the sleeve ()3 against movement. A nut 65 likewise has a screw driver nick (35 by which the nut may be screwed into place with the aid of a screw driver. The hubs 61 and 62 are threaded in opposite directions, forming right and left-hand screw threads so that a turning movement of the pinion 53 is effective to turn the threaded hub 61 in the threaded opening 60, and also to turn the threaded hub 62 in the sleeve 63, thus producing a longitudinal movement of the stem 425*, and cam carried thereby, in the bearing opening in which the stem is received. The threaded connection between the parts 62 and effects a bodily axial movement of the member 53 6l62 whereas the threaded connection between the parts 61 and 4:5 effects an independent movement of the member 45"-4:6. A removable pin 66 projects laterally from the stem 45 and is received in a slot 66" in the bearing portion 43 to guide the stem and the cam carried thereby and to limit them in their movement fore and aft of the machine. A rectilinearly movable actuating device 55 is provided with a finger piece 56, and is substantially cylindrical in form and moves within a vertically disposed cylindrical bearing opening 54 in the casting. A coiled expansion spring 58 is received within the opening 5%, and bears at its lower end against the bottom wall of the opening and at its upper end against thelower end of the actuating device 55*? This actuating device is provided with teeth 57, which mesh with the pinion 53 to effect a rotative movement of the latter to bring about an actuation of the cam 4E6 from the full to the dotted line position in Fig. 8. This movement is effected by the depression of thefinger key 56. Vhen pressure is released on the finger key the spring 58 is effective to restore it to normal position, thus reversing the direction of the rotation of the pinion 53 and withdrawing the cam 46 to the full line or inoperative position. In this construction a removal of the nut 65 enables the sleeve 63 to be unscrewed from the hub 62 and removed from the pinion 53. A removal of the pin 66 then enables the cam 46 and the pinion 53 to be withdrawn forwardly from the bearing opening.

In Figs. 11, 12 and 13 I have shown a still further modification of the resetting or restoring mechanism. In this construction the cam 4L6" is provided with a cylindrical stem 45 provided on one side thereof with rack teeth 67. The cylindrical stem of the cam is received in a corresponding bearing opening in the casting L3 and the teeth 67 engage a pinion 53 received in a transverse bearing opening 67 in the casting. The pinion is prevented from displacement from said opening by aremovable pin 68 received in an opening in the casting and engaging in a circumferential groove G9 in the pinion to prevent axial displacement of the pinion in its bearing open ing. This pinion 53 is in the nature of an elongated or double pinion divided centrally by thecircumferential groove 69, so as to form a left-hand end portion a, and a right-hand end portion Z). It is the lefthand end portion a of the pinion which engages the teeth 67 on the stem of the cam. The righthand end portion 6 of the pinion is engaged by teeth 57 which constitute a tick formed on one side of a rectilinearly moving vertically disposed actuating device or slide 55 mounted to move in a cylindrical opening in the casting and provided with a finger piece 56 The upper portion of the bearing opening in which the slide, or actuating device 55 is received is slightly larger than the lower portion so as to form a chamber to receive a coiled expansion spring 58 which bears at its lower end against the bottom wall of the chamber and at its upper end against a flange on the finger piece 56 The pressure of this spring is thus exerted to normally maintain the finger piece and the actuating device controlled thereby in the elevated position, thereby turning the double pinion 53 to move the cam to the inoperative position shown in Figs. 11 and 12. The parts are limited in their movements in this direction by the head of the cam bearing against the front face of the tabulator frame as indicated in Fig. 11. The forward movement of the cam is limited by the engagement of the finger piece 56 with the top of the tabulator frame.

From the fore oing description it will be understood that removal of the pin 68 enables the double pinion 53 to be removed from its open-ended bearing opening and to be disconnected from the actuating device 55 The actuating device is then free to be removed. from its bearing and the cam is free to be removed from its bearing.

It will be observed that in each of the constructions shown and described there is a resetting device, cam or wiper, a finger piece, and a rotative device intermediate the finger piece and cam for transmitting movement of the cam in order to move it into and out of operative position; that these parts in each instance are carried by the tabulator frame which is fixed to, and which for the purpose of the present invention may be regarded as a part of, the frame of the machine; that there is also a rectilinearly movable hand actuated device which moves a rack and transmits movement to a pinion which is operatively connected to the resetting cam or device; that otherwise stated there is in each construction a finger piece, a resetting device or cam and an intermediate geared connection or rack or pinion be tween the finger piece or cam for actuating the latter, or for moving it into or out of operative position.

It will be understood that various changes may be made in details of construction without departing from my invention.
